磁共振成像在乳腺癌影像学筛查中的应用:2010ACR与SBI乳腺影像学筛查实践指南解读

影像学能够在临床出现可触及肿块之前早期发现乳腺癌已经成为不争的事实.在多种影像学检查中,乳腺X线摄影是惟一被偱证研究证实的能够早期发现乳腺癌而降低死亡率的影像学方法,但由于存在局限性,因而近年来大量临床研究致力于评估乳腺磁共振成像及乳腺超声在乳腺癌筛查中应用的可行性和效能.为进一步提高乳腺癌早期检出率,乳腺癌筛查方案日...

Application of breast MRI in breast cancer screening: interpretation of the latest breast imaging screening guideline issued by ACR & SBI in 2010

It is well demonstrated that breast cancer is able to be early detected by imaging before palpated.Among all breast imaging modalities,mammography screening is the solely one that was demonstrated to reduce mortality of breast cancer.However,it is not perfect.Due to limitations of mammography,there have been many investigations to explore feasibility and validity of breast imaging beyond mammography,such as ultrasound and MRI.Consequently,screening protocols are getting more variable and complex.In 2010,American College of Radiology and Society of Breast Imaging updated the guideline of imaging screening,on the bases of board review of existed evidence and expertise consensus.Recommendations on screening using Mammography,Ultrasound and MRI according to breast cancer risk evaluation of women were issued.Specifically,breast MRI screening should be limited in high risk women.This article interpret the guideline,illustrate the contents,provide relevant evidence and knowledge and address some important points with authors sight,in order to help in Chinese medical practice.
